The linear regression shows that δ18O changes (0.9995‰ for benthic foraminifers and 1.022‰ for planktonic foraminifers) are equal to 100 m in sea-level fluctuation. After making temperature correction in the δ18O record of benthic foraminifers from 72 to 120 Ka B.P., the curve of sea-level oscillation of the South China Sea since 186 Ka B.P. has been reconstructed. The lowermost sea - level that occurred in the last glacial maximum and oxygen isotope stage 6 is approximately - 130 m.展开更多

Methods The data analyzed originated from 3 separate multicenter clinical trials with similar designs during 1994 to 1999. 166 patients with mean age 58. 9±9. 2 years were involved in Simvastatin Clinical Trial with simvastatin 10 mg once daily for 8 weeks. 146 patients with mean age 57. 9±8. 7years were involved in Lovastatin Clinical Trial with lovastatin 20 mg once daily for 8 weeks. 105 patients with mean age 57. 8±9. 3 years were involved in Atorvastatin Clinical Trial with atorvastatin 10 mg once daily for 6 weeks. Baseline total cholesterol (TC) was more than 5. 98 mmol. L - 1, and baseline triglyceride (TG) was less than 4. 52 mmo. L - 1. The patients were grouped by baseline lipid levels. Results The higher the baseline TC, low density lipoprotein cholesterol (LDL - C) and TG levels were, the more effective the simvastatin, lovastatin, or atorvastatin was in reducing serum TC, LDL - C, and TG, respectively. A positive linear correlation was found between baseline values and effects of simvastatin, lovastatin, or atorvastatin in reducing serum TC, LDL - C, and TG, respectively. Conclusion The changes of reduction on serum lipid with HMG - CoA reductase inhibitors in patients with hyperlipidemia were influenced by baseline lipid levels.展开更多

The prognostic impact of the preoperative and postoperative levels and chronological changes in CEA, CA19-9 and their combination were evaluated. To test whether postoperative adjuvant chemotherapy alters the prognostic impact of perioperative CEA and CA19-9 levels, the hazard ratios for mortality were compared between patients who underwent surgery alone and patients who underwent surgery followed by adjuvant chemotherapy.RESULTS The prognostic impact of postoperative CEA and CA19-9 was superior to that of the preoperative levels. Multivariable analysis identified high postoperative CEA and CA19-9 levels as independent prognostic factors for overall survival.Disease-free survival rates clearly decreased in a stepwise manner in association with postoperative CEA and CA19-9 levels, and patients with high levels of both markers showed significantly poorer prognosis than other patient groups. When we analyzed perioperative changes in serum CEA and CA19-9 levels, patients with high levels before and after surgery had the worst disease-free survival rates among all patient groups. Patients with normalized CEA levels after surgery had a significantly lower disease-free survival rate than those with normal perioperative levels, whereas patients with normalized CA19-9 levels after surgery had equivalent survival to those with normal perioperative levels. The prognostic impact of high CEA levels was observably smaller in patients who underwent adjuvant chemotherapy than in patients who underwent surgery alone, whereas that of high CA19-9 was greater in patients who underwent adjuvant chemotherapy. High postoperative CEA levels were significantly associated with an increased prevalence of liver, lung and bone recurrences, and high postoperative CA19-9 levels were significantly associated with increased frequencies of lymph node and liver recurrences.CONCLUSION The evaluation of serum CEA and CA 19-9 levels both before and after surgery provides useful information for precise risk stratification after curative gastrectomy.展开更多

The health authorities provided a considerable empirical evidence after this outbreak and it was notified that the causative virus, named Novel Coronavirus (subsequently SARS-CoV-2) is the culprit for progressively exerting grim effects not only on individual patients but also on the International public health, with high mutational tendencies. WHO declared nCOVID-19 as a Pandemic on 11<sup>th</sup> March 2020. The spike glycoprotein of SARS-CoV-2 plays a pivotal role in the entry of virus into the cell and it further interacts with ACE-II receptors which are widely distributed on the human cell surface especially on alveolar type II cells (AT-2) and endothelium. The mortality in nCOVID-19 patients is usually preceded by acute respiratory distress syndrome (ARDS) because of the cytokine storm. Advanced molecular biology and regenerative sciences renders a breakthrough in the treatment of severely ill nCOVID-19 patients with Mesenchymal Stem Cells (MSCs). Autologous or allogenic MSCs attenuate cytokine storm, improvise lung compliance, regulate inflammatory response, maintain functional alveoli microenvironment, promote endogenous regeneration and repair with no or minimal side effects. MSCs are naturally resistant to this novel Coronavirus. Even though it is corroborated with evidences from current clinical trials and pilot study, we emphasize the need for conducting more clinical trials with ethical consideration to prove the efficacy and safety of MSCs in combating nCOVID-19 infection and its complications.展开更多

Our results show （1） for 46 months （94%） of the studied 49 months it is found that for a given month, the distribution of the 13 pairs which come from the 13 solar cycles on a log Ri - Di plane may be fitted by a straight line with a correlation coefficient larger than the critical one at confidence level a = 5%, and for 36 months （73%） the fitting is even better, for a = 1%; （2） time variations of these two parameters and their correlations in the studied period can be described respectively by functions of time, whose main trends may be expressed by a linear or simple curvilinear function; （3） the evolutionary path of the level of sunspot activity may be represented by a logarithmic function as log/~ = 0.704 lnDi - 0.291.展开更多

However, the new arrived cognitive users may not be able to use the channel immediately since the channel usage state is random. This will impose additional time delay for the cognitive users. Excessive waiting delay can make cognitive users miss the spectrum access chances. In this paper, a discrete-time Markov queuing model from a macro point of view is provided. Through the matrix-geometric solution theory, the average sojourn time for cognitive users in the steady state before accessing the spectrum is obtained. Given the tolerant delay of cognitive users, the macro-based throughput is derived and an access control mechanism is proposed. The numerical results show the effects of service completion probability on average sojourn time and throughput. It is confirmed that the throughput can be obviously improved by using the proposed access control mechanism. Finally, the performance evaluations based on users are compared to that based on data packets.展开更多
